Fatigue tests were performed on two types of concrete, each proportioned for the same P8-day compressive strength one contained only "accidental" air, while the other contained intentionally entrained air which was maintained at a constant level. There was little variation in the ages of the specimens which were tested at stress levels of 50, 60, 70, 80, and 90 percent of the ultimate static compressive strength of the respective mixes. Within the limits of the investigation, the fatigue behavior of air-entrained plain concrete is similar to that of non-air-entrained plain concrete. However, the air-entrained concrete was more uniform than the non-air-entrained concrete with regard to both fatigue and static strength properties.
